| description | This paper presents exploratory problems of regularisation of the inverse method for the
investigation of the characteristics of acoustic sources at industrial conditions. The solution
of problem is to find an effective method for the determination of optimal regularisation parameters
in acoustic inverse problems. The sound power of the sound source distribution can
be simply deduced from the measured pressure field and the inversion of the corresponding
matrix of frequency response functions. The accuracy of reconstruction of the sound power of
the source is crucially dependent on the conditioning of the matrix to be inverted. The success
of regularisation depends on the appropriate choice of the regularisation parameter. |
